Pull-Push Rod

Abstract

The invention relates to a threaded device (7) embodied in the form of an anti-twisting stop which is rotatably connected to a traction-pressure rod. The inventive device comprises two oppositely located ratchet devices which are connected by a body enabling to stop the traction-pressure rod in several rotational positions with a predetermined locking force and, afterwards, to release it each time. Said threaded device (7) facilitates the mounting of the traction-pressure rod by the fact that the twisting should not be locked by additional handling, thereby making it possible to carry out a fine adjustment without additional measures. The ratchet device (4) comprises, for example, two ratchet elements (10, 11) provided with one or several catch lugs (12) or a metal or plastic ring part on one side and a gear rim on the other side. In addition, said threaded device can be provided with a spring element and a second anti-noise threaded device.
